FMCSA can revoke a carrier’s operating authority for a handful of reasons: an insurance lapse, a cancelled BOC-3, or a Conditional / Unsatisfactory safety rating from a compliance review. A missed MCS-150 biennial update is different: it deactivates the USDOT number, not the authority. The path back depends on the cause. For an insurance reinstatement, the request is prepared and submitted for you for $300, FMCSA fee included, once the new BMC-91 is on file; a safety-rating reinstatement requires a Corrective Action Plan. Operating while deactivated can draw civil penalties under 49 USC §14901.
What causes an inactive MC authority or USDOT number?
- Insurance lapse. When a BMC-91 expires or cancels and is not replaced within the 30-day cancellation-notice window of 49 CFR §387.313(d) (Form BMC-35), FMCSA revokes the authority.
- Missed MCS-150 biennial update. A missed biennial update can lead to civil penalties and deactivation of the USDOT number (49 CFR §390.19T(b)(4)). This deactivates the USDOT number, not the authority, and filing the update reactivates it. See our MCS-150 late filing guide.
- BOC-3 cancellation. If your blanket process agent cancels the designation, FMCSA no longer has a BOC-3 on file and the authority becomes inactive.
- Conditional / Unsatisfactory safety rating. After a compliance review, FMCSA can downgrade the rating. Unsatisfactory ratings impose a 60-day cease-operation order under 49 CFR §385.13.
- Voluntary revocation. The carrier filed Form OCE-46 to put the authority on the shelf, intending to reactivate later.
Each cause requires a different cure, so confirm the cause before filing anything.
How do I find out why my authority is inactive?
Before filing anything, look up the record in FMCSA’s Motus public search by USDOT number or company name. Check:
- Operating authority: active or inactive
- Insurance: whether a BMC-91 is on file
- BOC-3: whether a designation is on file
- USDOT number: active or deactivated
The combination tells you what to file. Inactive authority with no insurance on file means a new BMC-91. A deactivated USDOT number with the BOC-3 still on file points to a missed MCS-150. Inactive authority with insurance and BOC-3 both on file points to a safety-rating issue.
Use our USDOT lookup for a clean readout including the deactivation reason if FMCSA published one.
How do I reinstate authority after an insurance lapse?
Step 1: get a new BMC-91 on file. Your insurer re-binds the policy and files the BMC-91 electronically with FMCSA.
Step 2: if you file the reinstatement yourself, pay the $80 reinstatement fee to FMCSA via Pay.gov. The line item is “Reinstatement of MC Authority.” Many carriers use a service to avoid filing errors that bounce the application; our $300 MC authority reinstatement includes the $80 FMCSA fee, so you don’t pay it separately.
Step 3: FMCSA reviews the request. At fastreinstatementfiling.com, your reinstatement request is prepared and submitted for you once the cause is cleared; FMCSA controls how long approval takes. The price is $200 for a DOT out-of-service reinstatement and $300 for an MC authority reinstatement, which includes the $80 FMCSA fee.
Operating status during reinstatement
Interstate for-hire operation requires active authority, and brokers check status before tendering loads. Plan to keep the truck parked until FMCSA shows the authority active again.
How is a USDOT number deactivated for a missed MCS-150 fixed?
A missed biennial update can lead to civil penalties and deactivation of the USDOT number (49 CFR §390.19T(b)(4)). A USDOT number deactivated for a missed update is reactivated by filing the MCS-150 update. If the BMC-91 also lapsed during the same period, the authority needs its own insurance cure as well.
FMCSA enforcement is not automatic, but compliance reviews look back at periods of operation with an inactive registration.
How do I fix a cancelled BOC-3?
File a new BOC-3 at fastboc3filing.com. Your BOC-3 is filed promptly after you order. Once the BOC-3 and insurance are both on file with FMCSA (you can check both in Motus public search by USDOT number or company name), the authority can be reactivated. The cause was procedural rather than enforcement.
How do I upgrade a Conditional or Unsatisfactory safety rating?
The hardest path. After a compliance review, FMCSA issues a written rating. Conditional means the carrier can keep operating but must address violations. Unsatisfactory means cease interstate operation in 60 days unless upgraded.
The cure is a Corrective Action Plan (CAP) filed with FMCSA detailing every cited violation, the action taken to fix it, and verification (training records, new procedures, replacement vehicles, etc.). After the CAP is accepted, the carrier files a Request for Change to Safety Rating, which can include a new compliance review. FMCSA controls how long the review takes.
Costs run higher because the work is substantive. At fastreinstatementfiling.com, the CAP documentation is prepared and submitted for you — pricing depends on the rating and the scope of cited violations.
When is reinstatement not possible?
A small number of revocations cannot be cured because they go beyond regulatory non-compliance:
- Imminent hazard out-of-service order under 49 USC §521(b)(5). Issued when FMCSA finds the carrier represents an immediate danger to the public. The order must be appealed; an OOS due to imminent hazard does not cure on its own.
- Pattern fraud or false-statement findings from an OIG investigation. Reinstatement requires legal counsel.
- Failure to comply with a subpoena for records. Compliance plus a written explanation; FMCSA will then process a reinstatement.
In all three cases the path is professional — transportation lawyer, not a filing service. The cost difference is enormous.
How do I keep authority from going inactive again?
- Calendar the BMC-91 renewal date 60 days out. Switching insurers is fine; the gap between policies is what leads to revocation.
- Calendar the MCS-150 biennial update 30 and 7 days out. Nobody at FMCSA reminds you.
- Confirm the BOC-3 is in good standing annually. If the process agent goes out of business, you may not know until your authority deactivates.
- Run a CSA score check quarterly — see our CSA scores guide. A BASIC creeping over the intervention threshold is the warning before a Conditional rating arrives.
The deadline calendar tool handles the first three automatically by pulling FMCSA data and computing your renewals.
Should I reinstate or apply for a new MC?
In some revoked-authority scenarios, opening a new MC under a fresh LLC is simpler than reinstating the old one. That can be the case when:
- The carrier has a Conditional or Unsatisfactory rating that would require a multi-week corrective action plan.
- Multiple violations stack: insurance lapse plus missed MCS-150 plus a CSA spike, and the cumulative cure costs more than a new application.
- The original LLC has unrelated tax or liability issues that make a clean entity preferable.
The downside of starting fresh is the loss of years of clean inspection history, broker relationships tied to the prior MC, and any IRP / IFTA continuity. Most carriers with one or two years of operation prefer to reinstate; carriers in their first 90 days often find a fresh start cheaper.
Insurance companies typically rate “new entrant” carriers higher than a 2-year carrier, so the premium is also a factor in the decision. Get a quote from your insurance broker on both scenarios before deciding.
What do common reinstatement scenarios look like?
Three common patterns:
- The 31-day insurance gap. Owner-operator switched insurers, the new policy bound on the day the old one ended, but the old BMC-91 was processed as cancelled before the new one posted, and the FMCSA record showed the gap. Cure: refile BMC-91 plus reinstatement filing. Cost: $300 including the $80 FMCSA fee; insurance no extra. Timeline: FMCSA controls how long approval takes.
- The forgotten biennial. Two-truck fleet whose USDOT ended in 5; the biennial deactivation hit on a Friday; the carrier discovered it Monday morning when a load board showed them as inactive. Cure: file the MCS-150 update, which reactivates the USDOT number. Cost: $175 for the MCS-150 service.
- The conditional rating after a roadside cluster. A 5-truck fleet had three OOS roadside inspections in one quarter, drawing an off-site investigation that escalated to a compliance review. FMCSA issued Conditional. Cure: corrective action plan, in-person training documentation, vehicle maintenance system upgrade, request for change to safety rating. FMCSA controls the review timeline.
